After updating to 5.2, some pictures result in an exception when displayed with imageenmview. These pictures had been processed earlier with the imagevect component. This is the exception error message: Invalid operation with message Control '' has no parent window.
I sent the demo files and a jpg picture by mail. The picture had been annotated using imageenvect. With the demo compiled with imageen version 5.2, I get an error in the IDE (Delphi XE5) and the image is not shown. However with version 5.1 everything works fine.
